  • Patent number: 11484478
    Abstract: A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.
    Type: Grant

  • Patent number: 11259999
    Abstract: A method for making a toothpaste enabling enamel restoration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste over a long period of time without causing precipitation of calcium phosphate. When the toothpaste of the present disclosure is used in brushing teeth, the water-in-oil-in-water emulsions are ruptured under the effect of friction and pressing, releasing the soluble calcium and/or phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of remineralization of enamel and/or dentin exposed to the oral cavity.
